Building Electronics Kits at JOTA

Over the years a wide variety of electronic kits have been constructed.
Noisy ones like sirens, hee-haw sounds, monophonic organ, and so on.
Others have lights that flash in various combinations, such
as the image on the top left.

Arduino Sensor Gadget (2018)

The Sensor Gadget consists of a variety of tiny sensors, similar to
those found in a typical smart phone, connected to an Arduino Nano
processor. A small graphic screen displays the outputs.

The sensors include temperature, humidity, atmospheric pressure,
magnetic field strength, gravity and accelerometer, and an optional
light meter.

Arduino Programmable Synthesiser (2017)

Another old favourite returns this year, the monophonic organ. Pressing
on the piano-shaped keyboard with a finger plays the corresponding
note. Of course, this version is programmable, much like the Moog
Synthesiser from the 1970s. You can dial in a whole range of different
audio effects. With a bit of practise the audio possibilities are
amazing.

Programmable Bike Tail Lamp (2016)

For 2016 the bike tail lamp makes a return this year - with a twist.
It's now programmable using a DigiSpark Micro-controller, This is a
very small computer, the computer board measures just 23mm by 23mm! It
uses the same Arduino programming language and environment that we used
last year. It has four super-bright LEDs that can be flashed in any
combination you can think of.

Arduino Sampler (2015)

In 2015 the level stepped up a few notches, with the construction of
a tiny Arduino computer. The Arduino Nano comes pre-assembled on a
small circuit board which plugs into a larger sized board with light
emitting diodes, switches, potentiometer and other input and output
devices.

This kit is compatible with the Power House Museum's Thinker1 project,
so all the programming examples developed for the Thinker1 work on this
one. For more details have a look at our
Arduino Sampler pages.

Windmill (2014)

The return of a simple but effective circuit, the windmill, with light
emitting diodes that flash in a rotating pattern.

Cyclic Sounder (2013)

An audio tone that changes frequency with the flashing lights.
Sure to be loved by Scouts and hated by Leaders :)
